Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS02B100R0FS70 is determined by strict equivalence across the following parameters:

• Resistance value: 100 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package/Case: Axial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -65°C to 250°C
• Physical dimensions: 0.187" Dia x 0.560" L (4.75mm x 14.22mm)
• Number of terminations: 2
• Moisture resistance feature

The RS02B100R0FE70 meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RS02B100R0FS70 and RS02B100R0FE70 are active production components from Vishay Dale's RS series. The primary distinction lies in regulatory compliance status. The RS02B100R0FE70 carries ROHS3 compliance and REACH Unaffected status, while the RS02B100R0FS70 is RoHS non-compliant and REACH Affected. Selection between these equivalents should be based on applicable regulatory requirements for the end application and target market. Both parts are electrically and mechanically identical across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RS02B100R0FE70 be used as a direct replacement for RS02B100R0FS70?

A: Yes. Both components are parametrically equivalent across resistance, tolerance, power rating, temperature coefficient, operating temperature range, package type, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between RS02B100R0FS70 and RS02B100R0FE70?

A: The components are identical in electrical and mechanical specifications. The difference is regulatory compliance: RS02B100R0FE70 is ROHS3 compliant and REACH Unaffected, while RS02B100R0FS70 is RoHS non-compliant and REACH Affected.

Q: Are these parts interchangeable in PCB layouts?

A: Yes. Both parts share identical axial package dimensions (0.187" Dia x 0.560" L) and two-terminal configuration, ensuring compatibility with existing PCB footprints and through-hole mounting patterns.

Q: What determines substitution eligibility for this resistor?

A: Substitution requires equivalence in resistance value (100 Ohms), tolerance (±1%), power rating (3W), composition (wirewound), temperature coefficient (±20ppm/°C), operating temperature range (-65°C to 250°C), package type (axial), physical dimensions, and moisture resistance feature.

Q: Can lower-power or different-tolerance resistors substitute for this part?

A: No. Substitutes must match all specified parameters exactly. Deviations in power rating, tolerance, temperature coefficient, or operating temperature range disqualify a component from substitution.
